Doppler advice😬

Je
Hi ladies I need some advice .. I recently found baby on my at home Doppler over a week ago.. I went to the dr last week and they also found the hb on their Doppler.. I'm 10w4d still early i know but the past two days I haven't been able to find the hb 😔🙏🏼 this is my rainbow baby so of course I'm stressing out.. Please tell me that you've found it one day then the next you've had trouble?
